Then it will possibly trigger bad, because AFMT_CHANNELS() returns part 
of the old EXT channels, which is used in the HDAA driver. If you want 
to save time, you need to rebuild all of "modules/sound" only, w/o 
-DNO_CLEAN and doing "clean" first. The rest of the kernel is fine with 
-DNO_CLEAN.

Send output from bootverbose! Let's hunt this bug down :-)
